Extend SandboxMode enforcement from bash to the filesystem tools, the sandbox
RFC's deferred cross-family phase.
- dsh-sandbox-policy (new, ctx.sandboxPolicy): the single home for the
deployment default mode + workspaceRoot and the per-session override event,
renamed bash/sandbox-mode -> sandbox/mode and moved here with its fold/setter.
Decouples the bash seam from dsh-session.
- dsh-fs-sandbox (new): SandboxedFileSystem extends LocalFileSystem and fences
write/edit by the per-call mode (read-only denies, workspace-write contains to
the workspace + temp roots via the shared writableRoots, danger passes
through); reads pass through. Structured FS_SANDBOX_DENIED; in-lock parent
re-canonicalization. A policy fence in trusted code, not a kernel boundary.
- dsh-sandbox: the shared escalation kit (writableRoots, the strictly-wider
ladder, denial/hint markers, approveEscalation) both tool families use;
approveEscalation takes a structural approver so dsh-sandbox gains no
approval/agent dependency, and both tools stay duplication-free.
- tool-fs: write/edit advertise sandbox_permissions/justification under a
confining ctx.fs, map FS_SANDBOX_DENIED to the shared [sandbox: ...] marker,
and resolve the same one-approved-wider retry.
- examples/acp-agent: composes sandbox-policy + fs-sandbox, drops the gating
that disabled the fs stack under confined modes.
RFC docs/rfc/implemented/feature/2026-07-14-cross-family-fs-sandbox.md; the old
sandbox RFC's In-process/deferred/FAQ sections updated to shipped fact.
The existing assertion-only executable smoke proved selected outputs but could not detect drift across the integrated Python SDK, JSON-RPC notification stream, and persisted session shape.
Keep this separate from ACP snapshots because it must launch the actual platform-native packaged executable through the Python SDK. The deterministic model drives Cordis dynamic tool mounting, a Code Mode worker dispatch, direct spawn delegation, workflow-worker delegation, plugin disposal, and the parent/child persistence lineage.
Commit four portable goldens for the SDK result and three JSONL logs. Normalize timestamps, temporary paths, opaque session and agent identifiers, and bulky request headers while retaining ordering, tool names and arguments, header deltas, results, lineage, and final responses so all native build legs compare the same behavior.
Run the comparison in the label-gated executable build workflow and document the current coverage in the paired implemented RFC.
Add canonical Chinese bindings for build target, deploy root, peer
dependency, serving surface, wheel, wrapper, and VFS so future translations
have one source of truth. Apply the existing runtime, plugin, artifact, and
pipeline bindings throughout every Chinese counterpart touched by this PR.
Require the first Chinese use of peer dependency to retain the English term
so readers can map it back to the package-manager concept without
reintroducing mixed prose throughout the document.
Rewrite mixed-language prose where the English term is not an identifier,
while retaining package names, paths, flags, pkg, single-exe, and other
literal names exactly. Explain VFS on first use and keep technical constraints
readable without inventing compatibility terminology.
Describe single-executable worker support as implemented behavior, including
the filesystem-string entry contract and CommonJS worker artifact required by
the pkg loader, and remove the obsolete bundled-but-unsupported limitation.
Regenerate pairing fingerprints and the generated catalog reference so the
mechanical documentation gates validate the revised English and Chinese
pairs. This keeps the terminology table authoritative and prevents the two
languages from drifting as the runtime documentation evolves.
pkg stores application files in a virtual filesystem, and its
worker_threads hook discovers worker entry points only when they are passed
as filesystem strings. Convert the code-runtime entry with fileURLToPath()
and return the workflow built entry as a string while retaining its
source-mode data URL bootstrap.
Emit worker entry bundles as CommonJS .cjs files. pkg executes a VFS-backed
string-path worker through Module._compile, so an ESM-only entry can be
present in the executable yet still fail when launched. Keep the public hosts
ESM, adapt worker startup accordingly, and align exports, package file lists,
workspace constraints, documentation, and built-worker tests with the actual
artifact format.
Expand the custom-config executable smoke to load the Code Mode and workflow
plugins and script real run_code and zero-agent workflow calls. Require both
tools to return 42 from workers launched inside the pkg VFS, turning worker
support from an asset-presence assumption into an end-to-end runtime
contract.
Update the implemented RFC and verification gates to describe and exercise
the supported built-worker path. This adds no tool or JSON-RPC protocol shape;
it fixes how existing worker-backed capabilities are located and executed in
the single-file distribution.
